Eye tracking observers during color image evaluation tasks

Eye movement behavior was investigated for image-quality and chromatic adaptation tasks. examined the differences between paired comparison, rank order, and graphical rating tasks, and t examined the strategies adopted when subjects were asked to select or adjust achromatic regio indicate that subjects spent about 4 seconds looking at images in the rank order task, 1.8 seconds pe comparison task, and 3.5 seconds per image in the graphical rating task. Fixation density maps correlated highly in four of the five images. Eye movements gravitated toward faces and s introspective report was not always consistent with fixation density 5% of the time), they did so early. Foveations were directed to semantic features to adapt to the averag were directed to near-neutral regions, showing behavi
